BrewTinker - Brew Log

You brewed a great cup last week. This week you want to repeat it, but the grind, ratio, temperature, time, and bean context are already fuzzy. BrewTinker turns each brew into data you can review. It is not a social check-in app or a bloated coffee encyclopedia. It focuses on one job: keeping your brew records clear enough to guide the next adjustment. What you can do with BrewTinker: ◆ Record each brew quickly Save bean, recipe, grind size, dose, water, temperature, time, verdict, flavor tags, sensory scores, and notes. ◆ Carry the next adjustment forward Write down what to change next. The next time you brew that bean, BrewTinker reminds you first and pre-fills the parameters from your recent best cups. ◆ Brew step by step Bloom, pours and target weights are prompted for each method, and pour targets recalculate as you change dose and water. ◆ Compare controlled changes Run an A/B test that changes one variable at a time, then review which adjustment actually helped. ◆ See where you are at a glance Home shows this week's brews, your hit rate, and a one-line brief of the last cup. Tap it to jump to that day's record. ◆ Export data for deeper analysis Export all records, the current filtered set, or a date range. CSV includes grind, ratio, TDS, extraction yield, sensory scores, experiment labels, and more for Numbers, Excel, R, or Python. ◆ Local-first No account needed. Your records stay on your device, with no analytics or advertising SDKs. Available in English, Simplified Chinese, Japanese, Korean, and German. https://brewtinker.com/privacy/ https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
